Lucknow, July 29 - The author and publisher of a controversial textbook, that carries a picture of Prophet Mohammad, were Wednesday arrested in Uttar Pradesh for 'hurting the religious sentiments' of people, police said.

Karan Singh, author of Udayimaan Bhartiya Samaj ke Shikshak (Teachers in Emerging Indian Society), and R.P. Singh, owner of Lakhimpur-based Govind Prakashan, were arrested in Lakhimpur, about 100 km from state capital Lucknow. Karan Singh is a retired professor of the Ram Manohar Lohia Awadh University in Faizabad district.
